摘要
In the electromagnetic continuous casting of aluminium/magnesium alloy billets, defects in the form of vertical wrinkles and oxide deposits occur on the surface of the billet as a result of the greatly increased oxidation rate at the surface of the melt due to the presence of magnesium in the said melt and, given high requirements of the surface quality of rolled products, these make it necessary to mill the rolled surfaces of the billet. …??The said surface defects can be avoided by an oxide weir (26) which dips into the molten head (28), extends over at least the longitudinal sides (x1) of the inductor (12), is arranged approximately parallel to and at a distance (b) from the said sides and is moved backwards and forwards horizontally in its longitudinal direction (m). …IMAGE…
